My invention relates to statical refrigera tion, and more especially to refrigeratin devices involvin two receivers having sp erical or cylindrical form, both being connected by a ipe, in which is contained the refrigerating iquid. In the use of devices. of this kind for heating purposes and also for cooling purposes, an intense coldness is produced under very economical conditions but with serious inconvenience of handling and considerable effort in the manipulation results for the required purposes. I

In order that this type of refrigerating device heretofore mentioned should develop cold, reference being had tothe accompany ing drawing, the following manipulations are necessary:

First mam uZa-tz'on.The device should'be bodily lifte out of the refrigerator, the point A of the outer sphere A resting on the floor, and sphere E remaining elevated. In this position all the liquid that may be con tained in E passes in five minutes to A. This time can be reduced by covering the receiver E with a cloth soaked in hot-wateror pouring on E a small quantity offhot-water. The liquid runs rapidly through the pipe C and is deposited in its entirety in the sphere A; this being done, the:

Second mmnipulation, which is the hardest, is as follows: The device should be taken to a receiver containing fresh-water, part E' being placed in the water and part A remaining outside of the receiver. Under A is placed a fire whether emanating from kerosene, gas, electricity, etc. During the space of one hour and a half heating is effected, and

at the end of this period all the liquid con-V tion is .or rather willbe terminated in about 411,573, and in Argentina November 12. 1929.

10 to 20 minutes. Once this is finished, there should he proceeded with:

The third manipulatiomThe device is lifted and placed in an inverse position, that is to say: part E outside of the receiver and part A in the water. In doin so, the steam in the cupola B is condense and .;i.absorbs water from the receiver, thus remainin filled for the next operation: an interval 0 five minutes should be allowed to elapse before carrying out the:

Fourth mm'pulat z'om-The spheres should be lifted and taken back to the refrigerating chest, and thereafter is effected the:

Fifth manipwdatiom-The spheres should be lifted in order to be placed in the refrigerating chest through its top part. i This being done an intense cold is developed immediately, and at a cost less than $0.10 m/l there is obtained a very good and dry refrigeration during a period of 36 hours.

As may be observed, all this requires a great deal of work and effort, but acceptable by virtue of the infinitely low cost; on the other hand it is objectionable by reason of 7 the manipulations indicated on account of the excessive weight, impracticable for servants and house-owners. It always happens that ice-chests are placed in a position near to the dining-room, that is to say, in the centre of the house, but the receiver in which the spheres will have to be submerged, which must be cube of considerable size, the handling of kerosene water that is spilled on puttlng in and submerging the spheres, besides the odor from the combustible, debars such an operation from being put into practice in the centre of the house where the receiver for the immersion would have to be installed. For such reason, the'receiver in 9 diameter of the sphere E of the refrigeratback of the same, this valve also being not is a distance approximately of about 30 or met-res, and there may or may not be a room suitable for the manipulations and of hytions, excepting to apply water without anyperceptible effort, in the use of the devices for refrigeration. i In the accompanying drawing the view is a fragmentary Vertical sectional elevation of an ice chest constructed in accordance with the inventiomthe refrigerating device being positioned therein.

Referring to the drawing in detail, the two spheres A and E are joined by the ipe C and the welded shaft D. On thesp ere- A is welded a cupola B, which is provided with a blower F; at the left of this is a screw regulator for the blower. and further to the left a cover for filling water in, the steam cupola B before commencing to operate. Two small safety valves are welded on the part E, there being only one visible in the drawing. Another safety valve is welded on A at the visible in the drawing. V y

In the side of an ice-chest an opening is made, preferably somewhat larger than the ing device and of a height in relation thereto beyond its uppermost point, while'hinges are fitted at the point C of this opening to swingingly support a door that o erates in'a vertical path, as shown in the rawing by the arrow H, thedoor beingnormally retained in a vertical position by means of a suitable; latch. On this door is placed the receivers or spheres A and E of the device,

thus forming a part of the ice-chest. The part of the pipe C connecting the receivers that remains in the ice-chest is concentrically lined with inoxidizable plate, leaving a small space between the plateand the pipe. Orr facing the sphere the .plat e-covered pipe opens, reaching the sphere itself and fastening it as per I, J The parts K and L should be duly covered in order to avoidthe escape of water that will circulate in the space between the pipe and the plate. "Near to the part L, a hole of small diameter is drilled for the escape of impurities and for the outlet of t-hewater, which on the completion of the operation should be allowed to entirely drain oif, since plate or unsoldering of same. At the extreme N and the pipe 0 in which is placed at will a water-cock or nipple for adjusting a rubber pipe. Around the steam cupola B is soldered a metal hoop P, perforated with a mumber of small holes around the part soldered to the cupola...

Underneathpipe C is soldered a small pipe Q, from which branches off another of smaller diameter, on which is fitted another watercockor nipple adjuster. The position indicated in the drawing for these pipes has been elected with a view to the maximum visibility, but in practice this may be arranged in the manner most convenient.

Under the s here E is the receiver R constituting a sta ilizer for the water emanating from E. A drain-pipe S is fitted to this receiver and terminating at the upper end T in a plugof insulating material with holes or openingsinelined towards the top,

which serves as a siphon while the pipe S below the siphon conducts the water through U outside.

The siphon formed by the insulating plug has forits object; that once the circulation of water is terminated, freezing takes place thercinwhich automatically avoids the outlet of cold produced atthe base of K.

On the pipe U is fitted a font X of convenient width, depth and height, in order to allow the coupling therewith of a circular tray V of a diameter somewhat greater than A, with a lip extending into X that fastens on the side ofthe tray, the member Y is pro vided and supports the tray V, the latter being slightly inclined, to discharge the water in the trough as indicated by the arrow in the drawing. The said small trough can take the shape-0f a funnel and is fixed to the ice-chest.

avoiding the necessity of the labour of fitting and taking off the tray, reducing the manipw. lation of turning it to make room for the lamp or source of heating and inversely placing it under .A to receive the water.

. InZ is fitted an insulating fan, in order to avoid producing calefaction, the heat is transmitted to theice-chest. Everything being arranged as indicated, below is given the highest point; the draining of the interior water, because the temperature of this latter form in which it is proposed to eliminate the five manipulations hereinbefore described.

The tray V is removed and drawing back the latch that maintains the movable part of the ice-chest in a vertical position, turn it in the direction indicated by the arrow H, until the part A touches the floor. In this position the part E is elevated and is at the liquid is effected without the necessity of having to lift a weight of 18 kilos or more. The draining can be facilitated by a cloth steeped. in hot-water in order not to cause leakings. Having effected the draining, the device is again lifted, the water-cock is shifted and will remain in a vertical position, and latched. heat is applied below sphere A, and the current of water passes through 0, which on arriving at C impedes the transmission of heat from C to the ice-chest. The water falls to L and later goes out through K to the s )rinkler M, bathes the sphere direct or throng i the medium of the cowl made of cloth or fabric, and facilitates in E the condensation of the ammonia liquid. The water falls later onto the stabilizer, escapcs'through S without allowing the frigidity produced to escape later, and withoutthe least heat which it transports, being transmitted to the stabilizer from which it is isolated.

This operation should last an hour and a half, with the water constantly in circulation and of suilicient quantity; a quick refrigcration is effected, much quicker than that obtained previously by immersion in a vat of rises much more appreciably, thus retarding condensation and d minishing the effectiveness of the mechanism.

The evaporation having terminated in A, the temperature continues to rise. The water contained in B commences to boil and the steam generated escapes by the whistle announcing the fact that the operation will be completed in a few minutes time.

At the end of this period the current of water through Ois cut oil and it is initiated in Q. The water arriving produces the condensation of the steam in B, the vacuum absorbs the water, filling B for the next operation. The water continues running and overflows in the space limited by the crown and escapes through the holes made at the base thereof, bathing and cooling at A, falling later on in the small tray V, from there tothe small trough. and to the drainage U.

A having undergone this operation for five minutes, the water is cut off and freezing commences to be developed in the sphere E, causing a drop in the temperature of 19 to 20 centigrade in the course of an hour.

All that has been previously described has occurred without the operator suifering any inconvenience, the operations being effected in less time than under the manipulation house and to the spheres or cylinders them-' selves.

With this procedure is also'removed the risk of servants applying heat to the sphere E instead of A, which will immediately cause the deterioration of the refrigerator.

There can be eliminated the small trough, the tray V, the crown P and the pipe Q, destined for the refrigeration of A; in this case it would be sufiicient to place below A, a bucket of proper dimensions, containing water, and at the moment of effecting the refrigeration of A it should be raised until. the v'histle is submerged. This would. simplify the structure, but on the other hand an inconvenience is introduced and more effort is addcd to the operation.

The steam cupola may be dispensed With and to effect the calefaction with a naphtha or kerosene lamp, filled with a quantityof combustible equal to that which may be consumed during the period of-one and a half hours. At the expiration of this period, the lamp is extinguished by itself since the operation is completed, but without any indication that such is the case; this, however, can

be done by a procedure which will be thesubject of another patent, it being suflicient for the present to utilize an alarm clock whose bell will sound an alarm one hour and a half after the commencement of the calefaction.

The improvement described can be applied is to say, that required for lifting them, taking them out and placing them in a draining position and to again fit them to the icechest and proceed with the calefaction and circulation of water, avoiding the transportation of the refrigerating vat, i. e. the trip to the back of the house.

Resuming: There is a saving in effort, spilling of water-is avoided, the refrigerating vat is eliminated, transportation and deterioration through knocking about are excluded, time is economized, and a more efiicacious refrigeration is obtained, all of which have been demonstrated on numerous occasions.

The use of this type of refrigeration device is simplified in such a manner that it can compete with advantage with electric ice-chests, which latter While not requiring are susceptible'to breakdowns,

' er, and itsdaily consumptionin materia very high.
